Several studies have shown the amnestic effects of ethanol (ETOH). However, while memory tasks in rodents can be markedly influenced by anxiety-like behavior and motor function, ETOH induces anxiolysis and different effects on locomotion, depending on the dose. Verify the effects of ETOH in mice tested in the plus-maze discriminative avoidance task (PMDAT)(More)
Recently, we have described the antidyskinetic property of the GABA mimetic drug valproic acid on reserpine-induced oral dyskinesia, an animal model that has been related to tardive as well as acute dyskinesias, which are associated with important neuropathologies. The present study investigates the effects of different doses of the GABA mimetic(More)
The present study aimed to investigate the effects of sleep deprivation (SD) on the dose-dependent stimulant effect of ethanol (ETOH) on the open-field behavior of female and male mice. Sleep-deprived (48 h, multiple platforms method) or home-cage control female mice were treated with saline (SAL) or 1.4, 1.8 or 2.2g/kg ETOH 5 min before behavioral testing.(More)
The effect of home cage conspecifics' behavior on locomotor sensitization to amphetamine (AMP) or ethanol (ETOH) were investigated. Female mice were repeatedly treated with saline or AMP (2.0 mg/kg for 13 days--Experiment 1) or saline or ETOH (1.8 g/kg for 21 days--Experiment 2) in home cages where all the animals had the same treatment (homogeneous home(More)
The differential outcomes of social isolation and crowding environment on the effects of single or repeated administration of ethanol on open-field behavior were examined in female mice. Whereas housing conditions did not alter the increase in locomotor activity induced by ethanol single administration, behavioral sensitization (a progressive increase of a(More)
The present study was aimed at replicating, in a sample of Brazilian subjects, findings generated mostly in developed countries on the relative prevalence of alcohol problems, associated psychiatric disorders, family history of alcoholism and other familial psychiatric disorders in alcoholics and controls. A group of Brazilian male alcoholics (n = 103) and(More)
World population is becoming older, and aging is a common risk factor for a number of pathologies. In this respect, it is important to study possible factors that could modify alterations implicated in the process of aging. The aim of the present study is to verify the effects of social isolation on the expression of orofacial movements in adult and old(More)
Recently we have described the antidyskinetic property of the GABA mimetic drugs valproic acid and topiramate on reserpine-induced oral dyskinesia. In this respect, oral dyskinesia has been associated with important neuropathologies. The present study investigates the effects of different doses of the GABA(A) agonist tetrahydroisoxazolopyridine (THIP), of(More)
